Which of the following is NOT true of the F test? Choose the correct answer below. A. This test is very resistant to departures
from normal distributions. B. This test requires that both populations have normal distributions. C. This test compares two population variances or standard deviations. D. This test uses the F distribution.
A. This test is very resistant to departures from normal distributions.
Step-by-step explanation:
The Ftest or Fratio usually used to obtain the test statistic during hypothesis testing using the analysis of variance, is used to compare the equality or differences in population vatfuance or standard devuation. The critical values of the Ftest or Fratio is obtained using the F distribution table. When testing hypothesis using the F test, it requires that both populations follow a normal distribution.
Hence, the option, that F test is resistant to departures for normal distribution is not true of the Ftest.
